If your friend is good with a wrench, and parts are bought from Tischer, and you get a hold of some procedures, it shouldn't be that bad on the wallet for what you're about to do.

It's a tough break... Plastic guides are easy on the chain but when heat cycled over years in any vehicle (or even your oven if you tried) the stuff will get brittle.
